Review on ๐Ÿ”Œ Michigan Motorsports TPI TBI 3-Wire Heated Oxygen O2 Sensor Harness Adapter - Compatible with Iroc by Charles Chambers

Revainrating 5 out of 5

It works out. useful for sensors

This worked for me. I used it to replace my 1 wire O2 sensor on my 93 GMC K1500 with a 3 wire heated O2 sensor, ACDelco AFS74. The wire harness is connected correctly and the ends were long enough to connect to my electrical box on the engine bay side of the firewall. My truck idles smoother. I don't know if it's related to the heated sensor or just that the unheated sensor was old and needed replacing, but it's working better now so I'm happy. I will post a photo of the old and new O2 sensor with the wiring harness attached to the new one.

Pros
  • One year trial
Cons
  • Something is wrong
